A TTOC record for the volume listed as volser was not found with a valid MCV or MCT record in the CDS.
When copying a tape, the tape copy process fails this volume and continues with the next volume in the list. The tape cannot be copied.
If an original volume TTOC record is missing when replacing a tape, the tape replace process bypasses the volume.
If the previous or successor TTOC record is missing, all data set updates have been completed.
If the previous volume TTOC is missing, all data on the tape being updated is accessible except the first user data file on the tape. In this case, there is no problem associated with this tape because the data set cannot be accessed from this volume without first mounting the previous volume.
If the successor volume TTOC record is missing, all but the last data file on the tape being updated is accessible.
For both the previous and successor TTOC records, the records referencing the invalid data set are not modified.
For original TTOC records, verify that the volume serial is correct.
For previous volumes, no corrective action is required for this tape. However, this condition indicates a problem with the previous tape that should be corrected by the storage administrator.
For successor volumes, if the last data set on the tape is a valid migration copy, use the HDELETE command to delete the data set and recover a copy from another source. If the last data set on the tape is a valid backup copy, use the HBDELETE command to delete it.
